Hi!
Hi Pang Jin!
Sorry for not replying earlier, but I'm travelling and this is the first chance
in a week to read my email.
I own the original 2x converter for the SL. I had a chance to borrow a non-apo
converter for the R series. No appreciable differences noted, with several
lenses. (The original SL was sharper with certain lenses, the non-apo for the
R was sharper with others... nothing significant, either way.)
Then I bought the 400 f6.8 Telyt and found that this lens, with the 2x, gave
some noticeable vignetting in the corners. At the recent LHSA Spring Shoot,
here in Victoria, I had the chance to borrow an APO-2x from Leica's PRO-Pool.
I tried it on the 400 and found that there is virtually no vignetting with this
lens. Otherwise, I could see little significant difference between any of the
converters - other than the lingages for auto-aperture with the 'R' models.
Hope this helps!
Best Regards,
David.
